Hm, is that question too stupid or does noone know? ;-)

I have now downloaded file
W880_R8BA024_FS_EUROPE_1_RED53

What other files do I need? I haven't debranded my phone yet either and never flashed before so I am a little hesitant about the warranty loss until I know for sure that I'll be able to use all 3 languages that I need.

Could anybody help me out?
